God is the leading character throughout the Bible as He reveals Himself and His plan for us through His Word, yet there is one book of the Bible that never mentions Him by name. Which book is that?
Esther. The book only contains vague references to a higher power in control. For instance, in Esther 4:14, Mordecai says to Esther, "For if you remain completely silent at this time, relief and deliverance will arise for the Jews from another place, but you and your father’s house will perish. Yet who knows whether you have come to the kingdom for such a time as this?”
Why would the clearly Jewish author of the book not mention God? Gotquestions.org presents these three possibilities:
1. The book of Esther is about God working behind the scenes to preserve His people rather than through obvious miracles.
2. If the author was Mordecai, as traditionally thought, or another Jew in captivity, then leaving God's name out of the book would have protected them from the king's wrath and allowed the account of Esther to be spread.
3. The emphasis of the book seems to be on God's large-scope influence on historical events that made Esther the right person at the right time to save her people rather than focusing on direct, at-the-moment intervention.
Whether those explanations are sufficient or not, what's obvious from this wonderful book is that God takes care of His people, even through the darkest times of captivity, and He works in mysterious ways to save us.
